I was getting tired of all the warnings saying 'don't EVER do this' so I decided to post an answer.... Looks like I wasn't the only one either.
Linux won't properly support hot-pluggable systems until the root filesystem can be smoothly mirrored (and mirrors added/removed).
But that shouldn't be a big deal <evil grin>.
[I'm a computer techie these days at a shop that DOES deal with these systems. And they typically run Novell or SCO Unix or the like... or AS/400 or other even weirder OS's.]
It'd be fun if Linux could compete with these guys :) [soon - I know]
What's the status on UPS (uninteruptable power system) support? Can linux read commands from ANY UPS systems? (eg: Power is about to fail).
Or perhaps this is a power-management deal. Comment: If this IS APM-based, APM in non-laptops is GOOD to have! (required in laptops!) Just a pet peeve.... but it's a manufacturer problem (nonstandard APM) rather than a linux problem.
Wind to your wings! - Teunis
